(Cll 139-295) 3 Claims.V

This invention relates to loom temples, and more particularly to a means for making the temple adjustable to adapt it for use with various types of fabrics.

The usual form of temple comprises a structure to engage the cloth at the selvage during the weaving process to hold the cloth in an extended condition transversely of the warp. The cloth is guided through a cloth receiving space and brought into contact with temple rolls, which, in cooperation with other parts, causes it to follow a tortuous path through the device. The rolls have a holding efect on the cloth which maintains the cloth at approximately the same width as the warp threads have at the reed, and against the action of the filling threads, the resiliency of which tend to draw the warp 4threads together to reduce this width.

The extent to which the temple rolls will be effective for this purpose will depend upon the pressure exerted by the rolls on the cloth, and the path they cause the cloth to follow through the temple.

The action of the rolls can be controlled by changing their positions to vary the pressure they produce on the cloth.

Temples in which the parts were made ad- .instable to control the action thereof have previously been proposed. However, in such prior devices, the means provided to adjust the parts were diicult to manipulate, or were not constructed to give the precision of adjustment required.

It is an object of this invention to provide a -loom temple with a means for readily and accurately adjusting the parts to control the. action of the temple rolls on the fabric.

It is a further object of this invention tov provide a device which can be applied to an existing form of adjustable loom temples in wide commercial use to increase the ease and' accuracy of the adjustment of the parts thereof.

These and other objects mayibe attained by the structure illustrated in the accompanying drawing which is intended to show an exemplaryv modication of the device, although it will be understood that I do not. wish to be limited tothe specic structural details shown therein but wish to be free to.` use allV mechanical equivalents within the scope of the appended claims, and in which:

Fig. l represents a plan View of the head portion of the temple assembly. The temple is secured to the loom in a manner well known to the art and, therefore, it has not been thought necessary to illustrate this construction herein. Fig. 2 represents an elevational View of the head portion of the temple assembly, looking forwardly from the rear of the loom.

Fig. 3 represents the same View as shown in Fig. 2, but with some of the parts in section, taken approximately along the line III-III of Fig. 1.

Fig. 4 represents an end View of a portion of the temple head assembly, partially in section, taken along the line IV-IV of Fig. l.

In the drawing, the temple head assembly l is mounted on a temple bar 2, which is connected to the loom in a well known manner.

In the illustrated embodiment of the invention the assembly comprises a base portion, or pod, 3, which may be integrally connected to the temple bar, a temple top portion 4, and a top end 5. The top end is xedly secured to the base portion by a bolt 6, and the temple top is adjustably mounted on the top end, in a manner to be explained subsequently.

The temple top carries a plurality of temple rolls 1 and 8, which are rotatably mounted on roll pins 9 and IU, respectively. The pins may be secured is depending ears formed at each end of the temple top, as shown at Il and l2, Fig. 3.

The upper surface of the pod is formed with two cylindrical concavities I3 and i4 to accommodate the temple rolls, and they are formed by a ridge I5 which extends upwardly for a limited distance between the rolls.

When the temple is placed in an operative position on the loom, the fabric F, Fig, 4, is

'engaged by the temple between the D001 and the temple'rolls, being led over the lip I6 on the rear of the pod, beneath, and in Contact with, the

-temple roll "l, over the ridge l5, beneath, and in contact with the temple roll 8, thence over the lip I7 on the front of the pod and hence out of theA temple. In this manner it is caused to assume a tortuous course through the temple and 'in contact with the temple rolls. I

The positions of the temple rolls relative to the pod will determine the amount of clearance ber has a vertical surface |79 abutting the projection on temple top. The abutting vertical surfaces of both members are in slidable contact, and may be formed with inter-engaging parts, as at 20, to constrain the sliding motion to the vertical direction.

The temple top is attached to the top end by means of bolts 2l and 22 which pass through elongated openings 23 and 24, respectively in the portion I8 and are screw threadedly connected to the top end. f

The proportions of the parts are such that, when the bolts 2l and 22 are in a loosened condition, the temple top can be moved vertically,

relatively to the top end and the pod, to control the relative positions of the temple rolls to the pod. When the desired adjustment has been attained the bolts may be tightened to hold the parts securely in position.

The structure as thus far described is known to the art. However, with such a device, in order to make an adjustment it was necessary to loosen the bolts 2l and 22 and either strike the temple top downwardly to increase the pressure of the rolls, or insert a tool between the temple top and pod to force the topi upwardly to decrease the pressure. The results of such a crude method of adjustment were necessarily uncertain, and it was diiiicult to adjust the parts the exact amount needed for proper operation.

By my invention I provide a means to adjust the parts readily and accurately so that the temple rolls can be made to engage the cloth with the desired amount of pressure.

To this end a vertical hole 25 is formed between the abutting vertical surfaces of the temple top and top end member so that a part 26 of it is in the temple top and a part 21 in the top end, as shown in Fig. 3. That part of the hole in the temple top has screw threads formed in it to receive similar threads on an adjusting screw 28. The part of the hole in the top end member is made suiiiciently large in diameter so that the adjusting screw is freely rotatable therein. The top of the adjusting screw is formed with a head 29 which bears upon the top surface of the top end, as at 30, and may be provided with a kerf 32 to receive an adjusting tool.

If we assume that the adjusting screw has right hand threads thereon with complementary threads in the temple top, with the bolts 2| and 22 loosened, as the screw is rotated in a clockwise direction, the head of the screw will abut the top surface of the top end member to prevent the screw from moving vertically downwardly and therefore the reaction of the screw threads will cause the temple top to be drawn upwardly relative to the top end.

Since the temple rolls are attached to the temple top, they also, will be drawn upwardly relative to the pod thereby decreasing the pressure with which the temple rolls contact the cloth.

If the adjusting screw is rotated in a counterclockwise direction it will be retracted from the hole 25. In this case, the vertical travel of the screw can be controlled so that when the temple top is depressed enough to again place the head of the screw in contact with the top surface of the top end member, the temple rolls will be exerting the proper pressure on the cloth.

The amount of adjustment, therefore, is controlled by manipulating the adjusting screw, and the ease and accuracy afforded by this means in comparison to that previously used is obvious.

To apply this novel means for adjustment to prior loom temples of the type previously described, it is necessary merely to form the hole 25, with a portion thereof in the temple top and screw threaded, and a portion in the top end and of a larger diameter freely to receive the adjusting screw 28, and to assemble the screw in the device. By this means the old form of loom temple is readily converted into the improved device.

It is apparent that the same means for ad- 'justment could be applied to the pod of the temple, if desirable, rather than to the temple top and the same advantageous results would be obtained.

Having thus described a preferred embodiment of my invention, I claim:

1. A loom temple comprising a supporting member having a pod rigidly attached thereto, a temple top positioned above said pod and having formed thereon a vertically disposed surface, a vertically disposed surface on said supporting member complementary to and abutting the first said vertically disposed surface, an adjusting means rotatably mounted in the vertically disposed surface of the supporting member and screw threadedly connected to the vertically disposed surface formed on the temple top, whereby the temple top may be adjusted in vertical position relative to the pod, and means for securing the relatively movable parts in adjusted position.

2. A temple head assembly comprising a pod element xedly connected thereto, a top element positioned above said pod element, temple rolls rotatably mounted in one of said elements, said top element having a vertically disposed surface slidably bearing on a vertically disposed surface formed on a portion of said temple head assemblyy a longitudinal hole formed between and partially in each of said vertical surfaces and disposed in a vertical direction to accommodate an adjusting screw, said screw being freely rotatably mounted in the part of the hole formed in the said portion of the temple head assembly and engaging screw threads formed in the part of the hole contained in the top element, and means to limit the vertical displacement of said screw relative to the said portion of the temple head in at least one direction, whereby, upon rotation of said screw, said top element may be adjusted in a vertical direction relative to said pod element.

3. In a loom temple a supporting member, a base portion attached thereto, a top portion containing temple rolls, said top portion having a vertically disposed surface slidably abutting a vertical surface on the supporting member, an `adjusting screw inserted in a hole formed between said vertical surfaces, said screw being screw threadedly connected to said top portion and freely rotatable in said supporting member, means on said screw abutting the top surface of said supporting member to limit the vertical travel of said screw relative to said supporting member, whereby, when said screw is rotated, said top portion will be adjusted vertically relative to said supporting member, and means for securing said top portion iixedly to said supporting member in the adjusted position.
